Solubility in Binary Solvent Mixtures:  Anthracene Dissolved in Alcohol + 2-Methyl-1-butanol Mixtures at 298.2 K

Abstract

Experimental solubilities are reported for anthracene dissolved in seven binary alcohol + 2-methyl-1-butanol solvent mixtures at 25°C. The alcohol cosolvents studied were 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol, 3-methyl-1-butanol, and 2-pentanol. Results of these measurements are used to test a mathematical representation based upon the combined nearly ideal binary solvent (NIBS)/ Redlich-Kister equation. For the seven systems studied, the combined NIBS/Redlich-Kister equation was found to mathematically describe the experimental data to within an overall average absolute deviation of approximately (0.4%.

“…58 appeared in print, there have been several experimental solubility studies involving anthracene dissolved in organic solvents. Acree and co-workers [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] have measured the solubility of anthracene in four linear alkanes (nonane through dodecane), in two dialkylbenzenes (1,2-dimethylbenzene and 1,3-dimethylbenzene), in several primary (methanol, ethanol, 1-pentanol, 2-methyl-1-butanol, 1-hexanol, 2-methyl-1-pentanol, 1-heptanol, 2-ethyl-1-hexanol, 1-decanol, 3,7-dimethyl-1-octanol, 1,2-ethanediol, and 2,2,2-trifluoroethanol), three secondary (2-pentanol, 4-methyl-2-pentanol, and cyclopentanol) and one tertiary (2-methyl-2-propanol) alcohol(s), in four alkyl alkanoates (methyl ethanoate, propyl ethanoate, pentyl ethanoate, and methyl butanoate), in three ethers (2,2′-oxybispropane, 2-methoxy-2-methylpropane, and 1,1′-oxybis[2-methoxyethane]), in three chlorinated alkanes (dichloromethane, trichloromethane, and 1-chlorohexane) and three halogenated benzenes (chlorobenzene, fluorobenzene, and (trifluoromethyl)benzene), in five alkoxyalcohols (2-ethoxyethanol, 2-propoxyethanol, 2-isopropoxyethanol, 2-butoxyethanol, and 3-methoxy-1-butanol) and in several miscellaneous organic solvents (methyl acetoacetate, ethyl acetoacetate, ethanenitrile, propanenitrile, butanenitrile, benzonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, morpholine, ethanolamine, propylene carbonate, hexanedintitrile (also called adiponitrile) and tributyl phosphate). The authors measured the solubility at only 298.15 K, and for most of the solvents there are no independent experimental measurements to compare the numerical values against.…”

“…Acree and co-workers [56][57][58][59][60] reported the solubility of anthracene in several binary alcohol + alcohol solvent systems at 298.15 K. The solvents included nine primary alcohols (1-propanol, 1-butanol, 2-methyl-1-propanol, 1-pentanol, 2-methyl-1-butanol, 3-methyl-1-butanol, 2-methyl-1-pentanol, 1-octanol, and 2-ethyl-1-hexanol) and four secondary alcohols (2-propanol, 2-butanol, 2-pentanol, 4-methyl-2-pentanol). There has only been a single experimental determination for the solubility of anthracene in each of the binary solvent systems studied.…”
